Usage Notes
Applicable equipment................ This instruction manual applies to the printed circuit boards with the version
(version numbers) numbers listed below. Boards with different version numbers will differ in
appearance, jumper pin locations, and other aspects. (See pages 3 and 4.)
VF5X-4514 M6585069P902
VF5X-4515 M6585070P902
Jumper pin settings......... .. ........ Jumper pins on the expansion terminal block board must be set according to
the functions of the board actually used. (See table 2 and descriptions of the
individual functions.) It is preferable to set the jumper pins before installing the
expansion terminal block board in the inverter.
Speed feedback...................... .. The speed feedback function cannot be used with inverters with CPU version
100. Check the version number of the inverter by displaying the ._. C PU
item in the Gr- .Uc group. The speed feedback function can be used with
versions 110 and later.
4
to 20 mA output...................... The 4 to 20 mA output circuit outputs a current of about 40 mA for 1 to 2 ms
when power
is first applied. Verify that the connected equipment can handle
this current. However, the output voltage will not exceed 26 V.
Relay contact output .. .. ... .. . .. . .. .. When using the expansion
terminal block board, use pin
PG (pulse generator) ................
speed feedback control
TG (tachometer generator) .......
speed feedback control
P24 on the inverter for the
power supply connected to pins
RCH and LOW on the inverter
itself. Note that these three pins
are standard equipment
on the
inverter. If
an external power
supply is used, sneak paths
and sneak currents may occur
and cause incorrect operation
in relays and open collector
output signals.
Do not set items := :: : and := C: .=: to the value •-: (PG pulse input). The
PG pulse input setting is used when the output frequency reference is set using
a pulse train. This value
is not intended for use with feedba ck signals.

2 Installation in the Inverter Unit
This expansion terminal block board is installed on the VF-AS control board. Use the following procedure to
install this board.
1. Verify that the input power has been turned off with the switch on the distribution panel.
2. Remove the inverter cover.
3. After the CHARGE lamp inside the inverter goes out, wait for 5 minutes. Then, using a tester that
can handle high-voltage DC potentials, verify that the capacitors have been fully discharged.
(Measure the voltage between the PA and PC terminals on the main circuit terminal block.)
Install the expansion terminal block board only after verifying that the capacitors are discharged.
4. Remove the lock screw CD and remove the control terminal block board @.
5. Insert the CN6Y connector on the expansion terminal block board into the CN6X connector on the
control terminal block board removed
in step 4.
6. Insert the expansion terminal block board using the following sequence. (See figure 2-1.)
1. Insert the expansion board into the right side of the control terminal block board as shown in the
figure. (See the enlarged view
in the figure.)
2. There are 4 large and small holes in the expansion terminal block board. Insert the protrusions on
the columns protruding from the support stand into the two large holes.
7. Lock the expansion terminal block board in place with the two screws provided with the expansion board
@ in the two smaller holes in that board. Tighten down the screw CD removed in step 4 to lock the
control terminal block board
in place.
(Verify that the control terminal block board's flat cable is correctly inserted into connectors CN2 and
CN2A.)
Caution: Be very careful not to damage the equipment when tightening down screws with a screwdriver. Also,
during installation, before turning
on the power, verify that the components on the board are
vertical and are
not coming in contact with the plastic panel. On the VF5X-4514, these
components include IC1 and Q1, and on the VF5X-4515, these components include IC1, Q1,
and
Q3.
Ifthere is any contact, correct the situation by adjusting the component positions by hand.
8. For units of up to 18.5 kW, there will be a wiring window at the left ofthe inverter cover. Refer to figure
2-1, and break open the window to create the wiring opening. After connecting the cables, install the
inverter cover.
Caution: If burrs are created around the edges of the window, remove those burrs before connecting the
cables. This is to prevent damaging the cables.

(2) For Two-Phase Pulse Input Signal Operation
The inverter output frequency and forward/reverse operation can be controlled from a pulse input
signal by using the two signal phases, A and
B, from the pulse generator.
<When the VF5X-4514 expansion terminal block board
is used>
Jumper positions: See figure 1-3, "VF5X-4514".
Jumper settings: See table 3-1 -6.
1. Set the JP1 jumper to the PGB position
2. Connect the pulse input signal among the PGA, PGB and CC pins on the
expansion terminal block board.
(PGA pin: phase A PGB pin: phase
B)
3. A discrimination circuit determines the direction (forward or reverse) from the two
phases (phases A and
B) from the pulse generator. The operating frequency
instruction and the forward/reverse commands are also discriminated. (See
figure 3-1-4.)
<When the VF5X-4515 expansion terminal block board
is used>
Jumper positions: See figure 1-4, "VF5X-4515".
Jumper settings: See table 3-1-6.
1. Set the JP2 jumper to the PGA position, the JP3 jumper
to the PGB position, the
JP4 jumper
to the A position, and the JPS jumper to the A position. If the
expansion terminal
bl ock board S7 /P12 pin is to be used as the pulse generator
power supply, set the
JP1 jumper to the P12 position.
2. Connect the pulse input signal among the PGA, PGB and CC pins on the
expansion terminal block board.
(PGA pin: phase A PGB pin: phase

3. A discriminati on circuit determines the direction (forward or reverse) from the two
phases (phases A and

If a 12-VDC pulse generator is used, the expansion terminal block board pins P12 and CC, which
provide a constant-voltage 12-VDC power supply output, can be used as the pulse generator
power supply.

[Wiring]
• Use shielded cables for the signal wiring.
• The main circuit lines and the signal lines must not be bundled together.
• We recommend using a wire size of 0.75 mm2 (18 AWG).
